2. Herbal Flea Spray to Get Rid of Fleas from Your House

If you have been thinking of a flea bomb loaded with chemicals to eliminate fleas from your house, you must reconsider once and give a try to this herbal spray instead. This homemade flea spray uses such ingredients as lemon juice and witch hazel. They are entirely safe for your pets and kids. Here’s the recipe for this herbal flea spray.

Get this:
Vinegar- 1 gallon (a little less than 4 liters)
Water- ½ gallon (a little less than 2 liters)
Lemon juice- 16 oz. (a little less than 500 ml)
Witch hazel- 8 oz. (a little less than 250 ml)
Fresh vacuum bag- 1

Home and Garden Sprayer- 1 (this sprayer should be able to hold at least 6-7 liters at a time)

Do this:

You need to do vacuuming and then spraying with the flea spray.
Collect everything that cannot be vacuumed and wash it at the hottest setting of your washer. This kills even the larvae and eggs of fleas.
Now vacuum properly. Vacuum each corner, upholstery as well as cervices with the help of various vacuum attachments. Use the fresh vacuum bag. This ensures unrestricted air flow. Debris that collects from earlier vacuuming may hamper smooth air flow.

Now mix vinegar, water, lemon juice and witch hazel.
Fill this liquid mix into the garden sprayer.
Spray using a heavy spray.
Spray your carpets, furniture, pet bedding, window sills, floors, every nook and corner of your house.
Do this daily for at least 2-7 days depending upon how bad is the flea infestation in your home.
When fleas become less noticeable, you may then repeat every 3-4 days and thereafter once a week throughout the flea season.
If you start using this non toxic spray just when the flea season is approaching, you will need to spray only once a week throughout the flea season.
